Katy Perry Devastated Over Ex-Boyfriend Johnny Lewis' Death

Katy Perry was devastated when she heard her ex-boyfriend, Johnny Lewis, had died.

The "Sons of Anarchy" actor was found dead in a driveway last week in Los Feliz, California after he supposedly fell from a rooftop or balcony.

According to the Los Angeles Times, the incident occurred on September 26, when Lewis beat his landlord Catherine Davis to death before also attacking a gardener at the home. He had been released from prison just five days earlier after being arrested on a number of charges dating back to January.

Perry dated the troubled actor briefly from 2005 to 2006. A source says the "Firework" singer had "good times" with him, but ultimately realized he was "trouble," so she eventually separated from him to get ahead with her career.

"It's really sad. She could never help him and couldn't [let herself] go in that direction," the source said.
